It will likely depend on why "you are not up to the mark."
These are performance related clauses to the contract. If through no fault of your own, it becomes apparent that you are not likely to succeed as you cannot maintain a reasonable standard of progress, then the performance "guarantee" provides for, and sets a limit on the financial compensation if the contract has to be terminated. Clearly the FTO would expect their selection procedures to mitigate this risk as it applies both to themselves and to their clients.
Whilst the "guarantee" provides a level of underwritten risk support, it is dependent on the reasons for the failure. If the candidate wilfully fails to engage in the requirements of the programme or fails to apply the required effort then it is unlikely to provide a blanket level of protection. As with all contracts it would be wise to read the detail.
